Even funnier still, was that the MSDN keys seemed universal to all Microsoft software that was released at the time, regardless of whether it was distributed under MSDN or not.

However, and as an aside, probably when Office 2007 gets released retail, I doubt these keys will work. And as to older versions, my Office 2k that used to require phone activation stopped doing so after the product was more then 3 or 4 years old, or so. Not sure what the state will be with Office 2k3 however after a lot of time has ellapsed. I guess after awhile (at least looking at my Office 2k distro), they cease to care...
